Carriage of Haemophilus influenzae serotype A in children: Canadian Immunization Research Network (CIRN) study.

Background: Haemophilus influenzae serotype a (Hia) has recently emerged as an important cause of invasive disease, mainly affecting young Indigenous children. Carriage of H. influenzae is a pre-requisite for invasive disease and reservoir for transmission. To better understand the epidemiology of invasive Hia disease, we initiated a multicentre study of H. influenzae nasopharyngeal carriage among Canadian children. Methods: With prior parental consent, we collected nasotracheal tubes used during general anaesthesia in healthy children following routine dental surgery in a regional hospital of northwestern Ontario and a dental clinic in central Saskatchewan. In northwestern Ontario, all children were Indigenous (median age 48.0 months, 45.8% female); in Saskatchewan, children were from various ethnic groups (62% Indigenous, median age 56.3 months, 43.4% female). Detection of H. influenzae and serotyping were performed using molecular-genetic methods. Results: A total of 438 nasopharyngeal specimens, 286 in northwestern Ontario and 152 in Saskatchewan were analyzed. Hia was identified in 26 (9.1%) and 8 (5.3%) specimens, respectively. In Saskatchewan, seven out of eight children with Hia carriage were Indigenous. Conclusions: The carriage rates of Hia in healthy children in northwestern Ontario and Saskatchewan are comparable to H. influenzae serotype b (Hib) carriage among Alaska Indigenous children in the pre-Hib-vaccine era. To prevent invasive Hia disease, paediatric conjugate Hia vaccines under development have the potential to reduce carriage of Hia, and thus decrease the risk of transmission and disease among susceptible populations. Addressing the social determinants of health may further eliminate conditions favouring Hia transmission in Indigenous communities.

Historique: L'Haemophilus influenzae de sérotype a (Hia) a récemment émergé comme une cause importante de maladie invasive, particulièrement chez les jeunes enfants autochtones. Il faut être porteur de l'H. influenzae pour contracter une maladie invasive et devenir un réservoir de transmission. Pour mieux comprendre l'épidémiologie de l'infection invasive à Hia, les chercheurs ont lancé une étude multicentrique sur le portage nasopharyngé de l'H. influenzae chez les enfants canadiens. Méthodologie: Après avoir obtenu le consentement des parents, les chercheurs ont recueilli les sondes nasotrachéales utilisées pendant l'anesthésie générale chez des enfants en santé après une chirurgie dentaire courante dans un hôpital régional du nord-ouest de l'Ontario et une clinique dentaire du centre de la Saskatchewan. Dans le nord-ouest de l'Ontario, tous les enfants étaient autochtones (âge médian de 48,0 mois, 45,8 % de filles); en Saskatchewan, les enfants provenaient de divers groupes ethniques (62 % d'Autochtones, âge médian de 56,3 mois, 43,4 % de femmes). La détection de l'H. influenzae et le sérotypage ont été effectués au moyen de méthodes de génétique moléculaire. Résultats: Au total, les chercheurs ont analysé 438 échantillons nasopharyngés, soit 286 du nord-ouest de l'Ontario et 152 de la Saskatchewan. L'Hia a été décelé dans 26 (9,1 %) et huit (5,3 %) échantillons, respectivement. En Saskatchewan, sept des huit enfants porteurs de l'Hia étaient autochtones. Conclusions: Le taux de portage de l'Hia chez les enfants en santé du nord-ouest de l'Ontario et de la Saskatchewan était comparable à celui du portage de l'H. influenzae du sérotype b (Hib) chez les enfants autochtones de l'Alaska avant le déploiement des vaccins contre le Hib. Pour éviter l'infection invasive à Hia, les vaccins pédiatriques conjugués contre l'Hia en cours de développement peuvent réduire le portage de l'Hia, et donc le risque de transmission et de maladie dans les populations susceptibles. Le fait d'aborder les déterminants sociaux de la santé pourrait contribuer à éliminer les conditions favorables à la transmission à Hia dans les communautés autochtones.

Cesarean Delivery and Vaginal Birth After Cesarean Delivery Rates in a First Nations Community-Based Obstetrical Program in Northwestern Ontario.

OBJECTIVE: To examine rates of cesarean delivery (CD) and vaginal birth after cesarean delivery (VBAC) and the patient profile in a community-based obstetrical practice. METHODS: Retrospective data from 2012 to 2017 for the Sioux Lookout Meno Ya Win Health Centre (SLMHC) were compared to data from the 30 hospitals providing the same level of services (Maternity 1b: maternity care by family physicians/midwives with CD and VBAC capacity) and Ontario. SLMHC VBAC patients were then compared to the general SLMC obstetrical population. Data included maternal age, parity, comorbidities, CD, VBAC, neonatal birth weight, and Apgar scores. RESULTS: The SLMHC obstetrical population differed from comparable obstetrical programs, with significantly higher rates of alcohol, tobacco, and opioid use and a higher prevalence of diabetes. CD rates were significantly lower (25% vs. 28%), and women delivering at SLMHC chose a trial of labour after CD almost twice as often (46% vs. 27%), resulting in a significantly higher VBAC rate (31% vs. 16%). Patients in the VBAC population differed from the general SLMHC obstetrical population, being older (7 years) and of greater parity. The neonates of VBAC patients had equivalent Apgar scores but lower rates of macrosomia and lower birth weights, although the average VBAC birth weight at 3346 g was equivalent to the provincial average. CONCLUSION: The SLMHC obstetrical program has lower CD and higher VBAC rates than expected, despite prevalent risk factors typically associated with CD. Our study demonstrates that VBAC can be safely performed in well-screened and monitored patients in a rural setting with emergency CD capacity.

A 5 year retrospective study of emergency department use in Northwest Ontario: a measure of mental health and addictions needs.

OBJECTIVE: The main objective of this study was to understand the five-year trend in total emergency department (ED) visits, frequency of use, and diagnoses and disposition of patients. Since the region has experienced a profound increase in opioid use disorder since 2009, we were particularly interested in changes in the volume of mental health and addiction (MHA) ED presentations. METHODS: Retrospective aggregate data analysis of ED visits to the Sioux Lookout Meno Ya Win Health Centre 2010-2014. RESULTS: ED visit volume increased 29% over the five-year study period, while MHA ED visits increased 73%. The admission rate remained stable at 6.9% of ED visits. Five-year trends in clinically grouped diagnostic categories identified respiratory, MHA, and abdominal/pelvic complaints as the three most common ED presentations. In 2014, MHA presentations accounted for 10.3% of ED visits, 8.7% of admissions, and 20.0% of inter-hospital transfers. CONCLUSION: The dramatic increase in MHA ED visits mirrors the opioid epidemic the region is experiencing. MHA may soon become the commonest ED presentation. If reasons for ED visits serve as a proxy for unmet outpatient needs, increased efforts at developing community MHA services and addressing the related social determinants of health are required.

Community-associated methicillin-resistant Staphylococcus aureus in northwest Ontario: A five-year report of incidence and antibiotic resistance.

BACKGROUND: The incidence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is traditionally high in remote areas of Canada with large Aboriginal populations. Northwestern Ontario is home to 28,000 First Nations people in more than 30 remote communities; rates of CA-MRSA are unknown. OBJECTIVE: To determine the CA-MRSA rates and antibiotic susceptibilities in this region. METHODS: A five-year review of laboratory and patient CA-MRSA data and antibiotic susceptibility was undertaken. RESULTS: In 2012, 56% of S aureus isolates were CA-MRSA strains, an increase from 31% in 2008 (P=0.06). Reinfection rates have been increasing faster than new cases and, currrently, 25% of infections are reinfections. CA-MRSA isolates continue to be susceptible to many common antibiotics (nearly 100%), particularly trimethoprim/sulfamethoxazole, clindamycin and tetracycline. Erythromycin susceptibility stands at 58%. DISCUSSION: Rates of CA-MRSA, as a percentage of all S aureus isolates, were higher than those reported in other primary care series. The infection rate per 100,000 is one the highest reported in Canada. Antibiotic susceptibilities were unchanged during the study period; the 99% susceptibility rate to clindamycin differs from a 2010 Vancouver (British Columbia) study that reported only a 79% susceptibility to this antibiotic. CONCLUSION: There are very high rates of CA-MRSA infections in northwestern Ontario. Disease surveillance and ongoing attention to antibiotic resistance is important in understanding the changing profile of MRSA infections. Social determinants of health, specifically improved housing and sanitation, remain important regional issues.

HISTORIQUE: L'incidence de Staphylococcus aureus résistant à la méthicilline d'origine non nosocomiale (SARM-ONN) est généralement élevée dans les régions éloignées du Canada aux fortes populations autochtones. Ainsi, 28 000 membres des Premières nations habitent dans plus de 30 communautés éloignées du nord-ouest de l'Ontario. On n'y connaît pas le taux de SARM-ONN. OBJECTIF: Déterminer le taux de SARM-ONN et les susceptibilités aux antibiotiques dans cette région. MÉTHODOLOGIE: Les chercheurs ont effectué une analyse quinquennale des données de laboratoire et des données des patients à l'égard du SARM-ONN ainsi que de leur susceptibilité aux antibiotiques. RÉSULTATS: En 2012, 56 % des isolats de S aureus étaient des souches de SARM-ONN, soit une augmentation par rapport aux 31 % de 2008 (P=0,06). Le taux de réinfection augmentait plus rapidement que le taux de nouveaux cas : 25 % des infections sont désormais des réinfections. Les isolats de SARM-ONN continuent d'être susceptibles à de nombreux antibiotiques courants (près de 100 %), notamment le triméthoprim-sulfaméthoxazole, la clindamycine et la tétracycline. La susceptibilité à l'érythromycine est de 58 %. EXPOSÉ: Le taux de SAMR-ONN, à titre de pourcentage de tous les isolats de S aureus, était plus élevé que celui déclaré dans d'autres séries de soins de première ligne. Le taux d'infection sur 100 000 habitants est l'un des plus élevés à être signalé au Canada. Les susceptibilités aux antibiotiques demeuraient inchangées pendant la période de l'étude. Le taux de susceptibilité de 99 % à la clindamycine diffère de celui de seulement 79 % obtenu dans une étude de 2010 menée à Vancouver, en Colombie-Britannique. CONCLUSION: Les chercheurs ont constaté un taux très élevé d'infections par le SARM-ONN au nord-ouest de l'Ontario. Il est important de surveiller la maladie et de demeurer attentif à l'antibiorésistance pour comprendre l'évolution du profil des infections par le SARM. Les déterminants sociaux de la santé, particulièrement l'amélioration des logements et des mesures d'assainissement, continuent de représenter d'importants problèmes régionaux.

Delivering away from home: the perinatal experiences of First Nations women in northwestern Ontario.

INTRODUCTION: Our objective was to understand the perinatal knowledge and experiences of First Nations women from northwestern Ontario who travel away from their remote communities to give birth. METHODS: A systematic review of MEDLINE, HealthSTAR, HAPI, Embase, AMED, PsycINFO and CINAHL was undertaken using Medical Subject Headings and keywords focusing on Canadian Aboriginal (First Nations, Metis and Inuit) prenatal education and care, and maternal health literacy. This qualitative study using semistructured interviews was conducted in a rural hospital and prenatal clinic that serves First Nations women. Thirteen women from remote communities who had travelled to Sioux Lookout, Ont., to give birth participated in the study. RESULTS: We identified 5 other qualitative studies that explored the birthing experiences of Aboriginal women. The studies documented a negative experience for women who travelled to access intrapartum maternity care. While in Sioux Lookout to give birth, our participants also experienced loneliness and missed their families. They were open to the idea of a culturally appropriate doula program and visits in hospital by First Nations elders, but they were less interested in access to tele-visitation with family members back in their communities. We found that our participants received most of their prenatal information from family members. CONCLUSION: First Nations women who travel away from home to give birth often travel great cultural and geographic distances. Hospital-based maternity care programs for these women need to achieve a balance of clinical and cultural safety. Programs should be developed to lessen some of the negative consequences these women experience.

Traditional First Nations birthing practices: interviews with elders in Northwestern Ontario.

OBJECTIVES: Traditionally, First Nations maternity care was provided by community-based midwives trained through apprenticeship. Obstetrical practices and beliefs were integrated to provide holistic care. The Sioux Lookout Meno Ya Win Health Centre has a mandate to be a centre of excellence for Aboriginal health care. We undertook a literature review and performed a qualitative research study to understand some of the traditional practices in maternity care. METHODS: We conducted qualitative semi-structured interviews in English and Oji-Cree with 12 elders who had knowledge and experience of historical birthing practices in their home communities. Research team members included nursing and medical personnel and Anishinabe First Nation members. Interviews were analyzed and themes developed and verified by member checking and triangulation. RESULTS: The hands-on training for a community-based midwife often began in her teenage years with observation of childbirth practices. Practices were handed down by oral tradition and included prescriptions for healthy diet and moderate exercise during pregnancy; intrapartum care with preparation of clean cloths, moss, and scissors; the involvement of certain supportive family and community members; careful attention to the sacred handling of the placenta and umbilical cord; and careful wrapping of the newborn in fur. Complications, sometimes fatal, included retained placentas and stillbirths. CONCLUSION: The provision of modern maternity care to Aboriginal patients should include acknowledgement of, and respect for, traditional birthing practices. Facilities providing care for these patients should consult with the relevant Aboriginal communities to understand their needs and initiate appropriate programming.

First Nations women's knowledge of menopause: experiences and perspectives.

OBJECTIVE: To understand and describe the menopause experiences and perspectives of First Nations women residing in northwestern Ontario. DESIGN: Phenomenologic approach using in-depth qualitative interviews. SETTING: Sioux Lookout, Ont, and 4 surrounding First Nations communities. PARTICIPANTS: Eighteen perimenopausal and postmenopausal First Nations women, recruited by convenience and snowball sampling techniques. METHODS: Semistructured interviews were audiotaped and transcribed. Themes emerged through a crystallization and immersion analytical approach. Triangulation of methods was used to ensure reliability of findings. MAIN FINDINGS: This study confirms the hypothesis that menopause is generally not discussed by First Nations women, particularly with their health care providers. The generational knowledge gained by the women in this study suggests that a variety of experiences and symptoms typical of menopause from a medical perspective might not be conceptually linked to menopause by First Nations women. The interview process and initial consultation with translators revealed that there is no uniform word in Ojibway or Oji-Cree for menopause. A common phrase is "that time when periods stop," which can be used by caregivers as a starting point for discussion. Participants' interest in the topic and their desire for more information might imply that they would welcome the topic being raised by health care providers. CONCLUSION: This study speaks to the importance of understanding the different influences on a woman's menopause experience. Patient communication regarding menopause might be enhanced by providing women with an opportunity or option to discuss the topic with their health care providers. Caregivers should also be cautious of attaching preconceived ideas to the meaning and importance of the menopause experience.

Rural and remote obstetric care close to home: program description, evaluation and discussion of Sioux Lookout Meno Ya Win Health Centre obstetrics.

PROBLEM BEING ADDRESSED: Aboriginal and non-Aboriginal women in rural and remote settings struggle to access obstetric care close to home. Objective of the program: To deliver a full range of modern and safe obstetric care to 28 remote Aboriginal communities served by rural-based health care. PROGRAM DESCRIPTION: Rural family physicians provide intrapartum, cesarean delivery and anesthesia services to 350 rural, primarily Aboriginal women in a collegial, supportive environment. CONCLUSION: Rural and remote obstetric services need support before they fail. Patient volume, remote location and organizational culture are key elements. Evidence teaches us that outcomes are best when women deliver closer to home.

Palliative care of First Nations people: a qualitative study of bereaved family members.

OBJECTIVE: To understand cross-cultural hospital-based end-of-life care from the perspective of bereaved First Nations family members. DESIGN: Phenomenologic approach using qualitative in-depth interviews. SETTING: A rural town in northern Ontario with a catchment of 23 000 Ojibway and Cree aboriginal patients. PARTICIPANTS: Ten recently bereaved aboriginal family members. METHODS: Semi-structured interviews were conducted, audiotaped, and transcribed. Data were analyzed using crystallization and immersion techniques. Triangulation and member-checking methods were used to ensure trustworthiness. MAIN FINDINGS: First Nations family members described palliative care as a community and extended family experience. They expressed the need for rooms and services that reflect this, including space to accommodate a larger number of visitors than is usual in Western society. Informants described the importance of communication strategies that involve respectful directness. They acknowledged that all hospital employees had roles in the care of their loved ones. Participants generally described their relatives' relationships with nurses and the care the nurses provided as positive experiences. CONCLUSION: Cross-cultural care at the time of death is always challenging. Service delivery and communication strategies must meet cultural and family needs. Respect, communication, appropriate environments, and caregiving were important to participants for culturally appropriate palliative care.

End-of-life issues for aboriginal patients: a literature review.

OBJECTIVE: To understand some of the cross-cultural issues in providing palliative care to aboriginal patients. SOURCES OF INFORMATION: MEDLINE (1966 to 2005), CINAHL, PsycINFO, Google Scholar, and the Aboriginal Health Collection at the University of Manitoba were searched. Studies were selected based on their focus on both general cross-cultural caregiving and, in particular, end-of-life decision making and treatment. Only 39 relevant articles were found, half of which were opinion pieces by experienced nonaboriginal professionals; 14 were qualitative research projects from nursing and anthropologic perspectives. MAIN MESSAGE: All patients are unique. Some cultural differences might arise when providing palliative care to aboriginal patients, who value individual respect along with family and community. Involvement of family and community members in decision making around end-of-life issues is common. Aboriginal cultures often have different approaches to telling bad news and maintaining hope for patients. Use of interpreters and various communication styles add to the challenge. CONCLUSION: Cultural differences exist between medical caregivers and aboriginal patients. These include different assumptions and expectations about how communication should occur, who should be involved, and the pace of decision making. Aboriginal patients might value indirect communication, use of silence, and sharing information and decision making with family and community members.
